Rose plant JACcor

ABSTRACT

A hybrid tea class rose having strong fragrance, large open flowers and long pointed buds, thick petals, long stems, very vigorous upright growth and novel coral pink flower color.

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing an unnamed seedling, with the variety Showstopper, U.S. Plant Pat. No. 4,851.

The primary objective of this breeding was to produce a new rose variety having the large fragrant flower of the seedling parent coupled with the long stems and high production of Showstopper. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Strong fragrance.

2. Large open flower and long pointed buds.

3. Thick petals.

4. Long stems for a garden rose (18 to 22")

5. Very vigorous upright growth.

6. Novel coral pink flower color.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color description using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.

I claim:
 1. A new and distinct variety of rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its long bud, large open flower, thick petals, strong fragrance, vigorous growth, unusual flower color and excellent cutting stems.
